WINDOW-SHUTTER.

Specification of Letters Patent.

Patented July 13, 1909.

Application filed November 30, 1908. Serial No. 465,064.

To all whom it may concern:

Be it known that I, FREDERICK E. DOBF SCHEIT, a subject of the Emperor of Germany, and resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Im- -provements in \Vindow-Shutters, of which the following is a specification. Hy invention relates to new and useful improvements in shutters for windows such as are designed to be attached to the outside of a window casing, and to be operated from the inside without the necessity of opening the window.

It is the purpose of my invention to design a shutter which will be applicable for attachment to any of the common forms of windows, and employed in part to shade a portion or all of the window as occasion may require further to construct it so that it may be tightly closed and locked in such position as against not only the elements of the weather but persons as well, and thus 'form a protection against burglars.

As will be noted from the drawings and description to follow my invention comprises in part a suitable casing adapted for attachment to a window frame and provided with a series of slats mounted within the easing and adapted to be raised and lowered by suitable operating mechanism also contained within said casing. 'lhisopcrating device is designed to raise and lower the slats by the manipulation of a handle and is further connected with means for clamping and locking the slats shut.

Upon the accompanying two sheets of drawings forming a part of this specification similar characters of reference have been used to denote like or corresponding parts throughout the several figures and of which, f, Figure 1, shows an outside elevation of my improved shutter complete with front side of lower portion of easing removed, but otherwise in a closed and locked position. Fig. 2, 1s a similar view as seen from the outside of window but with the slats of the shutter partially; raised, the position of the mechanism for operating the same in a correspondingly changed position, and the lower part of the casing inclosing such mechanism shown in central vertical section: Fig. 3, is a sectional plan view taken on line 33 of Fig. 1. Fig. 4, is a similar sectional plan view taken on line 4-4 of Fig.2. Fig. 5, is an enlarged detailed vertical sectional view taken on line 5 of Fig. 1, illustrating the means for locking the slats in a closed. position. Fig. 6, IS an enlarged front elevation of the lower portion of the casing as shown in Fig. 1, but with the slat operating device in a different position. Fig. 7, is a similarly enlarge-d central vertical section of the lower part of the casing, somewhat like Fig.2 though with operative parts in different position, and Fig. 8, is a sectional plan view of the slat operating and locking devices as seen from line 88 Fig. 7.

Referring in detail to the characters of reference marked upon the drawings 10 indicates the shutter casing as a whole, which is adapted to be applied to-the outside of a window f ramc, with the face 11 of the casing secured to the surface of the window frame, while the operating shaft 12 would be extended through by means of the handle 13 attached to the inner end of the shaft which projects through a hole in the window frame 14-.

The vertical side )ortions. of the casing are boxed somewhat he that of the ordinary window frame and are provided with vertical slots 15 on the inner face of each side to receive the guide pins 16 of the slats 17 and whereby the same are permitted to be raised and lowered by mechanism later to be described and in perfect alinement with each other and the frame. There may be any desired number of these slats according to the size of window, and as shown they are connected together on their outside by a cord or chain 18 while the innerlower edges are,

similarly connected one with the-other by a pair of cords which is operatively connected one with the other by a pair of cords or chains 19, the upper endsof which are attached to the top portion of the frame as at 2-0, and whereby the slots are suspended one beneath the other.

A hood 21 which in practice would probably be made-of sheet metal is arranged over the upper end of the casing and forms an inclosure for the slats when the same are drawn to .their extreme upper position. An operating cord 22 is connected to the pin in the'ends of the lower slat and is carriedup through the boxes of the respective sides of the casing and over a roller 23 opcratively mounted. in the top portion of the casing, and is then brought down again through the same boX and under a similar roller 24 and connected with. the slat operating mechanism which will later be described. Thus it will be noted that while the cords 18 entirely support the slats when in the lower position, this operating cord 22 is made to support more or less of the slats according to the adjustment thereof, when raised. The lower slat 17 (see Figs.

1 and 5) is provided upon the inner face of each end portion with a notch 25 which when the slats are lowered will engage a hook 26 secured to the sides of the casing in a way to prevent the slats from being raised from the outside.

The means for raising and lowering the slats consist in a multiplicity of rolls and connected parts, divided into two separate sets of mechanism but connected to be simultaneously operated. This mechanism is arranged intermediate of a pair of side plates 29 secured within the lower part of the easing as shown in the several figures. These two sets of mechanism are connected to be operated by the shaft 12 through the medium of a handle 13.

27 indicates the two outer roll shafts which are mounted in the plates 29 and crosswise of the casing and one adjacent to each of the rolls 24. Each of these two shafts is provided with a series of grooved rolls 28 over which the cords 22 before mentioned are drawn.

30 represents slots of which there are two in both the front and back of the plates 29 to serve as guides for the movable roll shafts 31 which latter are connected at opposite 'ends with links 32 that are alike in construction.

These links in turn are connected to the opposite ends of the cross arms 33 mounted upon the before mentioned operating shaft 12. Upon the shafts 31 is also mounted a series of grooved rolls 34 which are operated in conjunction with the before mentioned rolls 28 upon the shaft 27 and serves to draw down or run up the cord 22 to operate the slats when the handle 13 and its shaft are manipulated. The purpose of this particular form of connection is to multiply the movement of the handle 13 as imparted to the shaft 12 sufficient to draw down the required amount of cord, namely, a length equal to that of the height of the window, by a half turn of the said shaft. The lower ends of the cords 22 are secured to the end rolls 34 and 35 upon the shafts 31 and they are each alternately guided back and forth over the successive rolls of the two series, and finally directed out under the roll 24 and up through the box of the casing as is clearly shown. From this construction it will be noted, that when the handle 13 and its shaft are operated as for instance in the direction indicated by arrow in Fig. 2, the inner shafts 31 will be drawn in toward the operating shaft 12 and away from the roll shafts 27 thereby rapidly drawing down the cord and lifting the slats so that when the said handle is thrown around to the opposite side as indicated in dotted lines in said figure the slats would have reached their uppermost position and also that the slats will be allowed to drop through the medium of the cord when the lever is thrown back to the opposite side or in its normal position.

In addition to the raising and. the lowering of the slats as already described I also provided means for turning to close the same from the position shown in the upper part of Fig. 2, and in Fig. 4, to that shown in Figs. 1, 3 and 5, which means consists of pivotal side clamps 36 which. are alike in construction, and as shown in cross section might be termed quarter rounds. Their two ends are pivotally connected to the upper and lower portion of the casing 10 as at 37 and 38, the pivoted point being formed in line with the inner corner while the rounded surface is permitted to operatively engage the concaved inner surface 39 of the corner of the box of the casing. This construction allows the said clamp to be swung back into the box out of the way with its shouldered edges 40 against the edge of the face of the box in a way to produce a neat finish and tight inclosure. Thesev clamps are obviously given substantially a,one quarter turn so as to throw them from the inner position as shown in Figs. 2, 4 and 8, to the outer or clamped position as shown in Figs. 1, 3 and 5, through connections with the handle 13 before mentioned as follows: Upon the lower pin 38 of. each clamp is mounted a "pinion 41 that is engaged by a suitable bent rack 42 which is inclosed within the lower portion of the casing above'the several rolls before mentioned and fitted to slide in guides 43 formed in the inner side walls of the lower portion of the box. The intermediate portion of this rack is provided upon its underside with a notch 44 designed to be engaged by a pin .45 carried upon a disk 46 mounted upon the before mentioned shaft 12. The position of this pin 45 in the disk with relation with the handle is such as to engage the notch 44 when the handle-is in the position shown at 13 in dotted line in Fig. 2, which would agree with a lowered-position of the slats. By raising the handle slightly from the position to that indicated by- 13 would serve to relax the cords and cause the pin to engage the rack and shove it over sufficiently to operate the connected gears and the clamps before mentioned. A detachable pin 47 may be inserted in. the window frame 14 under the handle 13 so as to hold the same and the clamps in position and prevent the latter from being operated from the outside, yet to allow the handle to be moved past for the operation. of the shutter, when the pin is detached.

In the foregoing operation theclamps engage the strips when in a partially closed position as shown in upper part of Flg. 2, in a way to press them down against each other as seen in Fig. 5, thereby snugly pressing the lower portion of one against the upper portion of the other and forming an absolutely tight shutter. The springs 48 connected intermediate of the casing and the rack obviously serve to hold the latter to one side in readiness to be engaged and operated by the pin 45, as shown in Fig. 7, against the action of the spring.

A second spring 50 connected intermediate of the casing and the arm 49serves to hold the parts in both an open and closed position.

The operation therefore of my device with the parts in position shown in Fig. 1, would be as follows; The handle 13 would be engaged and forced down, thus turning the shaft 12 and its disk 46 to release the rack which is then operated by the action of the spring 48 to throw back the clamps 36. With tiese clamps out of the way and by a continued movement of the handle from 13 to opposite side as seen in Fig. 2, the slats would be raised up back of thehood where- 1. In a shutter of the class described, the

combination with a casing having suitable guides on either side, of a series of slats hearing pins extended in the said guides of the I"; casing and adapted to be moved longitudinally therein, cords for connecting together and operating the said slats, a pair of rocker clamps adapted to be thrown around against the slats in a way to close and lock the same, a shaft for windim the cords to adjust the slats, and connections with said shaft for operating the clamps.

2. In a shutter of the class described, the combination with a casing having suitable guides on either side, of a series of slats bearing pins extended in the said guides of the casing and adapted to be slid longitudinally therein, cords attached to the said slats for raising and lowering the same, a multiple winding device for manipulating the cords to operate the slats and com rising an operating shaft, fixed and mova le roll shafts o eratively connected with the operating sha t, rolls upon the roll shafts and around which the. cords are laced for raising and lowering the slats by the turning of the operating shaft.

3. In a shutter of the class described, the combination with a casing, of a series of slats, connected together and suspended in a window casing, cord connections for raising and lowering said slats, fixed and movable roll shafts, a series of rolls mounted upon each of said shafts for said cord connections and around which the said cord is alternately drawn, an operating shaft, and connections thereof with the movable roll shafts for opcrating the same to and from the fixed shafts.
